Possible Side Effects:

There are no known contraindications for the use of Panacur Paste 10% in horses or cattle.

Side effects associated with Panacur Paste 10% could not be established in well-controlled safety studies in horses with single doses as high as 454 mg/lb. 1,000 mg/kg and 15 consecutive daily doses of 22.7 mg/lb. 50 mg/kg. At higher dose levels, the lethal action of fenbendazole may cause the release of antigens by the dying parasites. This phenomenon may result in either a local or systemic hypersensitive reaction varying in severity from itching or a rash to increased respiration and collapse. A veterinarian should be consulted if this type of reaction is suspected.
